Updating tomtom gps maps
You have an option to purchase either a one-time map update which currently costs €59 or lifetime map updates which costs €89.
If your sat-nav is over 3 years old, I would recommend the onetime update only.
In this case you can either select a smaller region that will fit on your device or you can insert a micro/SD card into your sat-nav to hold the maps. If you don't have one, you can purchase one from here. Always make sure you have the latest version of Garmin Express installed before updating your sat-nav. Unfortunately, Garmin Express does not always work.
On their website they ask to install a software, but Ubuntu is not supported (neither other linux distributions).Currently, all Tom Tom map updates are done through either My Tom Tom or Tom Tom Home.The free PC based software can be downloaded from here, `My Tom Tom for new devices and Tom Tom Home for older devices.It is important to let this procedure complete - don't be tempted to switch on/off your device even if it looks like nothing is happening.The software update procedure can take several minutes to complete so be patient. It is advisable not to update your sat-nav if the battery is flat, make sure it is charged. Your sat-nav may not have sufficient space for the map update.
Often (but not always), at three years the battery in the sat-navs start to deteriorate and as the lifetime map updates are not transferable to a new device, sometimes it can be more cost effective to replace the sat-nav with a new device rather than update it.
